TL;DR: Disclosed as discussed by the authors is a method of encoding a direct mode when coding moving images, the method includes finding a prediction and a cost for each of a plurality of direct modes including a backward-based temporal direct mode and a forward-time direct mode with respect to a current block to be encoded and determining one mode having the lowest cost as a result of comparing the costs as an optimal encoding mode, thereby performing encoding the direct mode.

TL;DR: In this article, a method and apparatus for encoding and decoding IPM information are provided, in which a coding unit is received, a plurality of sub-units included in the coding unit are determined, a relation between an IPM of each sub-unit and IPMs of neighboring sub units of the each subunit is checked, and information about IPM of a plurality this article.

TL;DR: In this article, an intra-prediction coding and decoding method is provided, in which a picture to be encoded is received in coding units, each of the coding units is divided into a plurality of sub-units, an IPM is determined for each coding unit, residual data is acquired for each sub-unit of each coding units according to the determined IPM, and information about the IPM of each coded unit and the residual data of each subunit of a coding unit are encoded.

TL;DR: The paper presents a new selective temporal error concealment algorithm (STEC) for error-corrupted H.264/AVC video bitstreams over the cdma2000 (or UMTS) air interface that provides PSNR gain up to 1.18dB and has an average PSNR improvement of 0.33dB under the FMO coding mode.
